Function diagram, function 

The refrigerant compressor (A9) driven by the motor compresses the refrigerant vapor which is heated up during the process, routed into the condenser (2) and thus cooled down.

The surface of the condenser (2) is used to withdraw the compression heat from the refrigerant. While cooling down, the refrigerant liquefies.

By flowing through the fluid reservoir with drier (3) the refrigerant is cleaned and dried of chemical and mechanical contaminants. The cooled and liquefied refrigerant flows through the expansion valve (4) into the evaporator (5), which is located in the fresh-air flow. The refrigerant is then vaporized. Through this evaporation process heat is extracted from the fresh air flowing past from outside over the tube and fin system so that air cools down.

The air humidity carried along is converted to condensed water, which escapes into the open. The air dries out.

The refrigerant compressor (A9) draws in the coolant which has turned gaseous through the collection of heat and compresses it again.

When the engine is running and the blower motor is switched on, the interior can be supplied with cooled air through the various air outlets. Cooling intensity is dependent upon the preset in-car temperature and blower setting.
